i just went to order heartworm pills for tayda and lenny online. my vet charges $62 per 12 month supply for each dog. If you order from petcarerx.com…. it is $48 per 12 month supply (free shipping) - but put them in your cart and then before checking out try to close the window. the window won't close and a window pops up offering you an additional 20% off… so i just got a 12 month supply for each dog for like $78
I suppose it would work for other things ordered from that site as well but i just did it for the heartworm... just thought I'd pass that along!
